History in Color did get their details wrong on this. This is not the 1912 East River escape (on July 7). This is actually from his July 15, 1914 escape at Battery Park. 15,000 people crowded the shore to watch, and Houdini had a close call, which I will detail in a future post.
Thanks to Axis Theatre Company for this find, and to MANTOO for catching the dating error.
